while i have my carbs out ...

while the carbs are out of the way, and the monsoons have let up for a bit, i have access to what looks like a coolant temperature sender and an oil pressure switch. is there any way to test these while the bike is not running ?

pull the temp sensor and put it in a stew pot on the stove 3/4 full of water.

with the burner on High, watch the pot.......... it will be the longest time ever, a watched pot always is.

When the water starts to boil, the thermostat should start to open.
206-212°F IIRC is the calibration for it.

98-101 °C is the exact range.

While I have never known either one on an 1100 to fail you can connect an ohm meter to the temp sensor put it in a pot of water and heat it, as the water heats the ohms should go down. If the oil pressure switch shows continuity to ground it's probably OK.

hi, AZ

are we talking about the same part ? you mentioned 'thermostat' but i am talking about the temperature sender mounted on top of the engine with a single wire going to it. my guess is that resistance changes as the unit heats/cools. i wanted to test it while carbs are out because i dont think it's remotely accessible while they are in. same goes for the oil pressure switch, but i don't know whether that one is an on/off type of thing or if it has varying resistance .
